Key Features of Free Video Converter
Convert Popular Video and Audio Formats for Free
Use the browser-based converter on this page for quick conversions of common video and audio formats. For larger local workflows, UniConverter Desktop adds broader format and codec support, batch conversion, output presets, and more control over resolution and export settings.
Popular video formats include MP4, MOV, MKV, AVI, WMV, M4V, WebM, VOB, 3GP, and more. Audio workflows include formats such as MP3, WAV, AAC, FLAC, AC3, and AIFF. The desktop Converter supports the broader format and codec matrix listed in the technical specifications.

Convert for Devices and Platforms with Desktop Presets
UniConverter Desktop includes output presets for phones, tablets, TVs, and other playback targets, helping you choose a compatible format without manually configuring every setting. Presets cover common iOS and Android devices as well as popular TV and media-device workflows.
Desktop output presets can also help prepare local video files for common web and social publishing workflows. For a quick browser conversion, use the upload tool at the top of this page; for batch jobs and more detailed output control, use UniConverter Desktop.
More Control Before You Convert on Desktop
A desktop conversion workflow often needs a little preparation before export. UniConverter lets you make practical adjustments to local files before converting them, so the output is closer to the result you actually need.
For example, you can merge clips, trim unwanted sections, crop the frame, adjust playback speed, and review output settings before conversion. Compression and other dedicated media tools remain available when the job goes beyond format conversion.
The desktop Converter also supports subtitle, audio, watermark, and basic effect adjustments as part of local conversion workflows. Use dedicated UniConverter tools when you need specialized tasks such as AI enhancement, speech processing, or advanced compression.
Free Online Converter vs. UniConverter Desktop
Both workflows convert media files, but they are designed for different jobs. Use the online tool for quick browser-based conversion and the desktop Converter when you need batch processing or deeper output control.
| Need | Online Converter | UniConverter Desktop |
|---|---|---|
| Quick one-off conversion | Best fit | Supported |
| Install required | No | Yes |
| Batch local files | Designed for quick browser tasks | Best fit |
| Broader format and codec controls | Basic online workflow | Available |
| Resolution and output presets | Basic output choices | More detailed controls and presets |
| Repeated local workflows | Good for occasional tasks | Better for frequent conversion work |
Free-version limits can apply to desktop workflows. Use the current Free vs. Paid comparison on this page for plan-specific details.

Add and Edit Subtitles
Among other merits, subtitles make videos considerably more engaging, and our platform allows you to add or edit subtitles for the videos you converted for free. Viewers are likelier to watch your videos once they see subtitles embedded in them.
Convert Speech to Text
Do you know some tools can convert your videos into text? Our speech-to-text tool transcribes speech from a video and makes it easily accessible for use in any way you wish.
Convert Video to GIF
Making GIFs has never been easier because, with our converter, you can snip any part of a video and turn it into a GIF in mere seconds. Plus, customize the frame rate, duration, and output size.
Crop, Trim, and Edit Clips
You can use our software to trim videos to a particular length, crop out unwanted sections or elements, and even increase or decrease the frame rate for smoother playback on specific screen sizes.
Enhance Any Video with AI
Leverage the power of artificial intelligence to edit old videos and make them look modern. The dedicated AI Video Enhancer provides separate workflows for improving clarity, reducing noise, restoring detail, and enhancing motion when conversion alone does not solve a quality problem.

If you’ve ever needed to use one image in multiple formats, use UniConverter's image converter to convert a picture into several formats, including the most widely used and popular ones, like PNG, BMP, TIFF, WEBP, SVG, EPS, and others.
